The retrospective study on the quality of malarial diagnosis and treatment in 4 district hospitals of Dac Lac province in 2001. Quality of malarial diagnosis: 100% patients tested for malaria, the positive slide rate was 58.3%, of which 93.1% with P.falciparum infected. Cases defination of WHO to confirm malaria diagnosis was not applied. There were 4 types of malaria diagnosis: malaria 26.8%, clinical malaria 28.8%, P.falciparum malaria 37.5% and severe malaria cases 6.0%. Quality of treatment: there were 8 treatment schedules used, of which 7 schedules were used for treatment of P.falciparum infection. More than 70% of the patients received treatment schedule with artemisinin derivatives and 66.6%-80% of them received full dose of treatment. The average time of treatment course was 2.5-4.5% days

Huong Hoa district of Quang Tri province is a high morbidity of malaria area, with 24% increased malaria cases than the same period of 2002. Due to: the mainly detection and treatment are passive methods, are not involved in commune and village health services. Protection method: 100% households were routinely protected by insecticide (house spraying or bednet impregnation), however, the local people were not alert to malaria can not prevent the contact betweens mosquito and people. The number of malaria cases in first 5 months of 2003 have been found to be increased compared to the same period of 2002. The number of cases in May has got higher than that in April

In recent years, although 2 technical measures (detection, treatment and vector control) were taken regularly and periodically for malaria control in Huong Hoa district, Quang Tri province, their effectiveness still weren’t satisfied, the positive slide rate was 6.9% during early 9 months of 2002 and 12.6% in 2003. The diversification of malaria endemicity: migration of population (exchanges, business, travel), habits of working and overnight in the forest, new settled dwellers, multiple species of vector… were affected interventional measures, so it was difficult to control effectively by primary health systems

Although the morbidity was sharply reduced in the last few years with the prevalence per 1000 population of 7.02%o in 1999, 4.37 %o in 2000…and the rate of population was protected by insecticide remained annual. The rate of population was protected by insecticide/population of malaria area was 58.6%o in 1999, 86.3%o in 2000. However, malaria has been increased by 31.6% during the first 9 months of 2003 as compared to 2002. Positive slide rate increased by 47% and parasite positive per patients increased by 64%. It is suggested that the activities for roll back malaria in the recent years have not been effective enough in accordance to the planned targets. It can also be attributable to the way of life of high risk groups such as swidden field sleeping, uncontrolled migration, the unsatisfactory coverage of insecticide protected people and poor management by local health

Study on 168 cases of traumas in the ear, nose and throat in Hue hospital during 1997-1998 has shown that the traumas occurred in all ages of which sinonasal traumas, ear traumas. The trauma due to traffic accidents, due to the accomodation and due to the working. The traumas in the ear, nose and throat usually combined with traumas in other regions

4189 persons in Phu Vang – Hue were enrolled in an inquiry on health and morbidity. Results showed that ear diseases account for 6.1%, among them media otitis trended to increase with children age; deaf and dumb 0.2%, dull 0.1%. In the right ear and left ear the incidence of media otitis was similar. Hearing capacity was less sensitive if it has media otitis of both sides. In children, extern otitis was preponderant, while in adult the main problems were buzzed ear, hearing loss, drum membrane perforation, mainly in the centre, then in ¼ infero anterior and ¼ posterioinferior, chronic media otitis 97.75%, acute 2.25%. About ¾ cases of media otitis lost hearing capacity, 28.5% had not been treated, 31.1% treated in commune health station, 25% in private physician office, 25.2% self treated at home, 18.7% in district and provincial hospital. In > 3 children family group, 81.6% and in > 5 children family group, 46.2% had media otitis

Designing technological process to assess bioequivalence of oral antibiotic products. Method: Choosing volunteers, setting experiment, taking specimens, following volunteers' health, quantifying cephalexine in specimens, and analysing experiment data. The method assessed by drug's hardness, accuracy, limitation of quantification, stability

A comparison study was carried out on 1,242 medical records of pharyngolaryngeal disease among pediatric inpatients with ages of 1 -15 in Hue Central Hospital and 2852 medical records of pharyngolaryngeal diseases among pediatric inpatients with the same ages in Aue hospital, West Germany. Results showed that the pharyngolaryngeal diseases were leading diseases among diseases of ear, nose and pharynx in both hospitals. The rate of these diseases treated by operation in Aue hospital was higher than this in Hue hospital. There was difference of the morbidity rate between age groups. The rate of treatment of infection disease and infections complication in Hue hospital was higher than this in Aue hospital. The Aue hospital considered in prophylactic operation, diagnosis and rehabitation better than Hue hospital. There was no death in Aue hospital while there were 6 deaths in Hue hospital.

Objective To explore the contribution of prenatal ultrasonic diagnosis to congenital digestive tract obstruction. Methods Prenatal ultrasonographic data of congenital digestive tract obstruction in 46 fetuses were retrospectively analyzed. Results Congenital digestive tract obstructions, including 1 esophageal atresia, 7 pyloric stenosis or atresia, 18 duodenal stenosis or atresia, 6 intestinal stenosis or atresia, 3 colonic atresia, 9 anal atresia and 2 congenital megacolon were proved with induced abortion or postnatal operation. Conclusion Prenatal ultrasonogrphy can directly depict the level and degree of digestive tract dilatation, therefore, is an important prenatal diagnostic modality of congenital digestive tract obstruction.
